Tone Parameter Syntax
Each tone is specified by nine integers, as follows:
ntone, freq0, freq1, level0, level1, steady, on-time, off-time, total-tone-time
•
ntone is the number of frequency components (0, 1 or 2).
•
freq[0] (Hz) is the transformed frequency of the first frequency component (-32768 to 32767).
Note
Only positive values can be configured to the Cisco ATA 186. For negative values, use the 16-bit
2’s-complement value. For example, enter -1 as 65535 or 0xffff.
2’s-complement value. For example, enter -1 as 65535 or 0xffff.
•
freq[1] is the transformed frequency of the second frequency component (-32768 to 32767).
•
level[0] is the transformed amplitude of the first frequency component (-32768 to 32767).
•
level[1] is the transformed amplitude of the second frequency component (-32768 to 32767).
•
steady controls whether the tone is constant or intermittent. A value of 1 indicates a steady tone and
causes the Cisco ATA to ignore the on-time and off-time parameters. A value of 0 indicates an on/off
tone pattern and causes the Cisco ATA to use the on-time and off-time parameters.

tone pattern and causes the Cisco ATA to use the on-time and off-time parameters.
•
on-time controls the length of time the tone is heard in milliseconds (ms) expressed as an integer
from 0 to 0xffff sample at 8000 samples/second.
